.SPECIFICATION forming part of Letters Patent No. 669,107, dated 'March 5, 1901.

Application filed August 5, 1899. Serial No. 726,243. (No model.l

To all whom t may concern.:

Be it, known that I, FRANCIS A.W1NsLow, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Windows, of which the following is a specification.

My invention relates to certain improvements in swinging windows, the Object being to construct the same of metal,to guard against wind, rain, and the like getting into the room, and to permit the windowsto be swunginto the room in order that both sides of the saine may be accessible for the purpose of cleaning, 85e.

To such end the invention consists in certain novel features of construction, which will be clearly described in this specification and the essential features thereof more particularly pointed out in the claim appended hereto.

The device is shown in the accompanying drawings by means of eight figures, of which-- Figure l is an inner face view of a pair of easement windows with their supportingframe. Fig. 2 is a horizontal section in line 2 2 of Fig. l with certain portions broken away. Fig. 3 is a similar section in line 3 3 of Fig. l. Fig. 4 is a vertical cross-section in line 4 4 of Figs. l and 2, certain parts being broken away. Fig. 5 is a section in line 5 5 of Fig. l, showing the right-hand window swung into an open position. Fig. (5 is an end View looking in the direction of the arrow 6 of Fig. l with certain portions broken away. Fig. 7 is a rear elevation of a portion of the frame and windows, and Fig. Sis a detail cross-section in line 8 8 of Fig. 2.

In the views, A A represent the vertical or upright members of the window-frame, A2 the upper member, and As the lower member, thereof. The side and upper members are formed with flanges d a a2 along their edges to strengthen the same, and the side members are formed with horizontal flanges a3 a4 at their upper and lower ends, respectively, as seen in Fig. 6, to which the upper and lower members A2 A3 are bolted. The member A3 consists, preferably, of a horizontal portion a5, having at its rear end an oiset portion a5, and down from the lower faces of the portions a5 a5 extend flanges a7 a5 a9. The

l upper and side members are each formed near their rear edges with inwardlyprojecting iianges A4 A5 A-, (see Figs. 2, 4, and 5,) from which project lugs a5. The vertically-extending flanges A5 A6 terminate at their lower ends in oblique portions ab, extending out t0 the edge of the frame, the object of the same being hereinafter more fully described.

The window-sash are seen at B B and consist of rectangular frames `b b', hinged to the vertical members A A of the window-frame by means of hinges C C4. The adjacent edges of the two Window-sash are formed with grooves b2 b3 and ribs b4 b5, the rib upon one sash being adapted to rest in the groove upon the other, as clearly indicated in Fig. 2, to shut out the wind, rain, &c. The rear edges of the sash are adapted to rest against the lugs a on the flanges A4 A5 A5 of the window-frame, and the sash are formed near the edges of theirouter faces with grooves b5, from the inner edges of which project rearwardlyexteudingflangesb7. rIhissurroundingange extends beyond the flanges A4 A5 A6 upon the Window-frame, and the grooves bare adapted to resist any rain which may beat in between the anges o7 and those upon the windowframe and -allow the water to run down between the flanges upon the window-frameand the window-sash.

The windows are locked in place by means of thrust-bolts D D', secured upon the sash B, at the top and bottom thereof, openings a5 a5 (see Fig. 5) being formed in the members A2 A5 of the frame to receive the bolts.

To prevent the rain from beating in between the window-sash and the lower member A3, bars E E are pivoted to the sashes by means. of eyes e, (see Figs. 4 and 7,) said bars resting againsta shoulder ad upon the lower inember A3 of the frame and held against the same by means of an upwardly-extending lug a5, formed upon the portion a5 thereof. The flanges 127 at the bottoms of the windows overhang slightly to protect the upper edges of the bars E E from the weather.

Then the sash are thrown open, the bars E E' swing upon the eyes, as seen in Fig. 5, their free edges resting upon riding-plates R, secured upon the horizontal portion a5 of the member A5 of the window-frame. These IOO riding-plates protect said member from being marred by the bars E E in passing over them. As seenin the drawings, the forward edge of the member A3 is rounded off, the forward edge of the riding-plate conforming thereto. When the windows are open to theirfull eX- tent, as seen in dotted lines in Fig. 4, the bars E E do not engage the riding-plates, but are suspended from the eyes e. When, however, the windows are swung into a closed position, the lower edges of the bars E E strike the rounded forward edges of the riding-plates and are tilted upward thereby until they again slide upon the upper faces of the plates. When the window is completely closed, they drop back of the shoulder ad.

The Window-panes are held in place upon the sash by means of soft-metal strips f, secured to the sash by rivetsf, (see Fig. 8,) said strips being bent up against the window-panes after they are putin place. Putty F is then sealer putin the angles formed by the window-sash and glass to make a perfectly waterproofjoint.

I claim as new and desire to secure by Letters Patent- A window comprising a frame having suitable Vertical and horizontal members, a pair of window-sash hinged to said frame, their free ends being formed with engaging grooves and ribs, thrust-bolts upon one of said window-sash adapted to engage the window-frame and swinging bars pivoted to the bottom of the sash and adapted to engage the lower member of the frame; substantially as described.

In Witness whereof I have hereunto set my hand, at Chicago, in the county of Cook and State of Illinois, this 2d day of August, A. D. 1899.

FRANCIS A. WINSLOW.
